High performance optics
A range of six lenses is available. From ultra wide angle
Grey------
at 0.75 : 1, designed for rear projection, to the super
tele zoom at 3.7 - 6.5 : 1 ratio. All lenses use special
hite------
LD (Low Dispersion) glass, and aspherical lens elements
manufactured to the highest possible standards, with very
high precision CNC-machined mechanical interfaces. All
lver-------
lenses feature lens shift both horizontally and vertically
to aid in installation without having to introduce digital
distortion and reduction of detail through the use of
digital keystone adjustment.
The precision projection lenses feature LD (Low Dispersion) glass and
aspherical lens elements to resolve the finer detail of a 1920 x 1080
HDTV image. High microcontrast provides an incredible image quality.
Patented DuArch™ dual architechture
technology uses two lamps, dual colour
wheels and dual light formatter paths for the
most efficient and highest performance single
chip DLP™ projection engine ever created.
The Sealed Optical Architechture molded
magnesium engine ensures a stable and reliable
chassis for the optics. With a high precision CNC
machined mechanical interface to the projection
lens, optimum focus is ensured at all times.
Infinitely adjustable output brightness
To match the Action! model three 1080 to any desired
on-screen brightness, each lamp's power is individually
adjustable, in addition to adjusting illumination apertures
with extremely high precision. This gives an infinitely
adjustable brightness, up to as high as 2500 ANSI
lumens, enough for even the largest screens.
RealColor colour management suite
Our proprietary RealColor colour
management suite ensures perfect
colour and grey scale reproduction,
and allows an easy and accurate way
to setting up. Each single projector
is individually calibrated during the final test phase,
recording actual performance, with colour gamut and
saturation, as well as electrical properties. This is then
applied to the incoming signal, in order to display any
format correctly. Each unit comes calibrated to a perfect
D65 white point.
True optical contrast vs sequential contrast
True optical contrast will always have full white level
and full black level available with any picture content. A
torch pointing at the camera in a dark environment will
have true, intense, white light, at the same time as the
dark areas will be just that. Sequential - or dynamically
enhanced contrast - on the other hand, will control the
output of the projector based on image content. Only
with bright content pictures will the projector have
intensive brightness. The dark environment may be
dark, but the torch will look more like a candle, as it
will not have an intensive output. With mixed exposure
scenes, a projector with dynamic contrast enhancement
will have neither bright, nor dark images, whereas true
optical contrast will have maximum available contrast at
all times, providing a much more dynamic image. Some
projectors try to overcome problems with varying output
levels by electronically compensating for it. This leads
to severe loss of detail, especially in bright parts of the
frame with mixed and low exposure scenes.
